>Description:
Up through 6.2 the system (a dell laptop latitude c540) with a dlink
airplus G dwlg630 (h/w ver c2, f/w ver 3.0) worked fine.  I updated to
7.0 (currently 7.0 Beta 4) and immediately when inserting the card the
system will report an interrupt storm at irq11 and provides no connectivity.
